How Exactly Does Data Scientists Analyze Data?
Data Scientists are the expert Data Science professionals who are equipped with all the advanced & the latest data analytical skill sets. They make use of advanced techniques to collect and analyze large sets of data. Data can be collected in many different ways including surveys, questionnaires, product specifications and sales data. In some cases, Data Scientists would be readily provided with which they need to analyze but in most of the cases Data Scientists need to collect data right from the scratch by using techniques like web scrapping.
Data is typically categorized into two broad categories: structured and unstructured. Structured data is the type of data you normally obtain from a traditional database such as a phone book or credit card billing records database. Unstructured data consists of raw or unprocessed data such as product manuals and sales receipts. Data Scientists are very much capable of handling both structured & unstructured formats of data.

How Data Scientists Analyze Data:
As stated earlier, a data scientist should have the ability to work effectively on all sorts of different data, including historical, and scientific information. It can be very difficult for a Data Scientist to learn about all of these data structures, without having some sort of formal training.
Data Scientists also use various tools to analyze the data and produce relevant reports. One of the most common types of tools used by Data Scientists is a mathematical & statistical formula. The most common mathematical formulas are linear regression, generalized linear models, k-means and least squares.
Other than these, various statistical techniques like the Bayesian and Fisher analysis are also used to generate useful results. By applying these techniques, Data Scientists are able to find relations among different items of data, identify patterns within the data.
